A bullet leaves a gun with a horizontal velocity of 100 m/s. Calculate the distance it would travel in 1.3 seconds.
2 answers:
<u>Answer:</u>
The bullet would travel 130 m in 1.3 sec
<u>Solution: </u>
The bullet leaves a gun with a horizontal velocity of 100 m/s
We know that the velocity means the distance travelled per sec
The formula for the distance with respect to speed and time is
Let us assume the bullet travelled distance S and the time is 1.3 sec
So,
Hence, the bullet travel 130 m in 1.3 sec

Answer:
The statement "if the magnetic force is always perpendicular to the velocity, the path of the particle is a straight line" is false.
Explanation:
The equation for the magnetic force on a charge q moving at velocity v on a magnetic field B is given by the (vectorial) Lorentz Force Law
From it we can clearly see that the <em>magnitude of the magnetic force </em>exerted on the particle is <em>proportional to the magnitude of the charge q and to the speed v of the particle</em>, and that it is also <em>perpendicular to the particle's velocity</em>. This means that at each instant it moves perpendicularly to the force, so <em>the work done by the magnetic force on the particle is zero</em>.
The statement "if the magnetic force is always perpendicular to the velocity, the path of the particle is a straight line" is false not only for this but for any force, a force always perpendicular to a velocity will curve the trajectory.
